Well, it actually IS possible, albeit it would need some careful
planning of course. Having said that, it's also the better solution,
since it's far easier to access Unix hosted VOBs from Windows
(either via Samba or NFS) than the other way round.
To get the VOBs (and views, you didn't tell what OS your view server
is) migrated to Linux, to could also apply for a temp. MultiSite
license, set up another CC region and replicate your VOBs to the
Linux VOB server in that region. Once the move is done and all
clients migrated, the MultiSite license is not needed anymore.
HTH...
